In the early 1960s, nearly all 18 to 26-year-old male U.S. citizens and most noncitizens living were required to register for the draft.
Because the Vietnam War was primarily a ground war, 82 percent of American servicemen who fought in Vietnam were members of the Army and the Marines, and two-thirds of those soldiers were drafted.
This was the first military draft in the United States since World War II. With capsules filled, they were poured into a tumbler and drawn, one-by-one, until all 366 dates were assigned a number. September 14th, April 24th, December 30th, and so on, until the last date, June 8th, was called.
A lottery drawing – the first since 1942 – was held on December 1, 1969, at Selective Service National Headquarters in Washington, D.C. This event determined the order of call for induction during calendar year 1970; that is, for registrants born between January 1, 1944, and December 31, 1950.

It was the first time a lottery system had been used to select men for military service in the US since 1942, and established the priority of call based on the birth dates of registrants born between January 1, 1944 to December 31, 1950.
All men of draft age (born January 1, 1944, to December 31, 1950) who shared a birthday would be called to serve at once. The first 195 birthdays drawn were later called to serve in the order they were drawn; the last of these was September 24.
